A-SL127-DG-G04D

Headers, Male Pins Overview

The A-SL127-DG-G04D is a board-to-board connector from the AW 127 series, manufactured by ASSMANN WSW Components. It features a single row of four contacts with a 2.54 mm pitch. Designed for through-hole mounting, this male right-angle header utilizes surface mount terminals for secure PCB attachment. The housing is constructed from polybutylene terephthalate (PBT) meeting UL 94 V-0 flammability standards. Electrical specifications include a rated current of 12A and a voltage rating of 100V. The connector operates within a temperature range of -40°C to +105°C, utilizing tin-plated bronze contacts.

Headers, Male Pins Feature Summary

• Right-angle design facilitates compact vertical interconnections between stacked circuit boards.
• Through-hole termination ensures robust mechanical stability and reliable solder joint integrity.
• High-temperature resistant PBT housing provides structural durability in demanding thermal environments.

Headers, Male Pins Applications

• Vertical stacking of printed circuit boards in modular electronic systems
• Interconnection of daughterboards to main logic boards in industrial control units
• Signal routing in telecommunications equipment requiring high-density connections

Headers, Male Pins Procurement Notes

Verify that the specific ordering suffix matches the required contact plating and housing color variants. Confirm that the right-angle orientation aligns with the mechanical constraints of the assembly enclosure. Ensure the through-hole pad layout corresponds to the manufacturer's recommended footprint dimensions to prevent soldering defects during wave or selective solder processes.

Headers, Male Pins Selection Notes

Select this component when a low-profile, right-angle connection is required for single-row signal transmission. The 2.54 mm pitch offers a balance between density and manufacturability. Consider the 12A current rating for power distribution applications within the specified voltage limits. The through-hole mounting method is preferred over surface mount when higher mechanical strength against vibration is necessary.

Headers, Male Pins Part Context

This part belongs to the AW 127 series, which focuses on standard board-to-board connectivity solutions. The series emphasizes reliability through standardized pin pitches and durable thermoplastic materials. ASSMANN WSW designs these connectors to meet international safety certifications, ensuring compatibility with global manufacturing standards for consumer and industrial electronics.

Headers, Male Pins Replacement Considerations

Direct substitutes must maintain the 2.54 mm pitch, 4-position count, and right-angle through-hole configuration. Verify that alternative manufacturers offer identical housing material properties and UL 94 V-0 ratings. Ensure mating pin dimensions are compatible to prevent mechanical interference during insertion.
